The value of internal energy change is - 37689J
Explanation:
The reaction is:
where,
= heat change at constant pressure = -50160 J
= heat change at constant volume or internal energy change = ?
= change in the moles of the reaction = Moles of product - Moles of reactant = 2 - 7 = -5 mole
R = gas constant = 8.314 J/mole.K
T = temperature =
Putting in the values we get:
